Along the ZMM Route Many Road–Side Signs Explain the Activities of Lewis and Clark.

….“We pass by a marker saying something about Lewis and Clark. One of them came up this way on a side excursion from the Northwest Passage. .. Nice sound. Fits the Chautauqua. We’re really on a kind of Northwest Passage too."

I-94 Rest Area 6 Mi West of Miles City, MT. Capt. William Clark, mentioned in sign, traveled this way. Because of all the reasons mentioned in the previous photo, the Yellowstone Valley, became the major East-West artery of Montana, and locus of commerce and larger towns.
….Since the Narrator’s goal was Bozeman, MT, we should not be surprised that the ZMM Route follows for 160 miles fairly close to a river which happened also to have been traveled by Capt. Clark.
….Moreover, both the Narrator and Lewis and Clark traveled West from Montana. Basically the facts of geography, lead/constrained the ZMM Route so that it repeatedly encounters Lewis and Clark Landmarks.
….The Chautauqua” mentioned above is the upcoming “lecture” by the Narrator. He will cover hierarchies of logic (inductive & deductive logic) as applied both science and mathematics. “Logic in action” is illustrated by mechanics of motorcycle maintenance and the physical organization of the motorcycle.
